Diamondbacks reportedly interested in free-agent starter Jordan Montgomery

Despite the Diamondbacks appearing to be done adding to the roster through free agency, recent reports have connected the Snakes to free agent pitcher Jordan Montgomery. Is there any chance Mike Hazen has enough left in the budget to acquire another Scott Boras client? Also, has Jake McCarthy become a sought-after asset and will the D-backs look to add another pitcher via trade instead of free agency?
